You may need knotting on the door as well.

Knotting Solution is a shellac or resin based sealer (brown/clear, respectively) which should be applied to the knots in timber before you paint it. It stops those horrible brown rings from showing through your paint a couple of months down the line.

Oops!

You can do a few things or just risk it and hope no knots bleed through (they usually do, though), assuming the door has knots.

You could use a primer that acts as a knotting solution such as Zinsser B-I-N (Ronseal also make one) before undercoating or sand back the knotty areas and apply knotting solution (may make the door look patchy) before re-priming. Another option would be Aluminium Wood Primer which blocks resins but I usually only use it on hardwoods.

The choice is yours.
